thats to aggressive for a base map. also use the lower octane timing map as a safety net.. clone your high octane map to it then highlight all the WOT area and retard 3-4* and it will do its job

on knock ecu uses low oct map so it should always be less then the high oct.

if its an evo 8 set the peak boost area to around 3-4* and end at 10* uptop for your base map.. baby steps.. otherwise you will fry the rings with detonation.

93 is easy to tune tho.. you know the drill.. when it knocks pull timing.. keep in mind you can cause knock also downlow with to little timing tho.

 

Thanks for the advice, that's a great idea for the low-timing map. I'll re-think my base map here, and maybe make it a little bit less aggressive

 

Well guys here's mine. Let me know what you think.



I'm thinking about pulling some timing in the low RPMs from 100-200 load to help aid in quicker spool-up. I'm hitting 26psi around 4100 and the car feels a little sluggish in the low RPMs. What do you guys think? My mods are in my sig. and I'll be installing a Grimmspeed 3 port tomorrow which should also help with quicker spool. Thanks for your input

 

Map looks pretty good to me Ian, wish I could run that much timing at cruise The 3-port should definitely help build boost faster; I hit 20 psi at 3k rpm in 3rd gear if I start my pull around 2k rpm.

 

I havent touched timing in cruise. How does more timing in cruise help? Smoother more power maybe. Does higher compression need less timing during cruise?

 

Thank you sir! I can't take a whole lot of credit though. Appauldd helped me out a ton with this tune by getting me going on a Tephra V.5.10 ROM so I give him most of the credit. Since then I've just been trying to dial it in and last week I converted over to a Tephra V.7 ROM.

I usually start my pulls at 2000 but I'm only hitting 9psi by 3K and then then it takes off and I'm at 20psi by 3500 and 25psi by 4000. So IDK. Maybe i'll just leave it where it is cuz it makes daily driving a lot easier and prolly better on gas too

As far as the timing at cruise goes that's all Appauldd there. I think he was trying to help out my fuel economy . The car cruises really good without any knock.

 

More timing increases power; so more timing at cruise increases fuel economy because you don't need to give as much throttle to maintain your speed. You can verify this by looking at your boost gauge while cruising; with more timing you'll have more vacuum, which indicates you're using less gas. More timing in the 60-90 load will give you better acceleration when just cruising around, also increasing fuel economy and making the car feel more "zippy"

 

Thanks Raptord. I learned something new today

 

This map is what I have on my Evo IX GSR now with:
Greddy EBC @ 21psi and TBE.

I have just added:
ETS Intake & LICP
Walbro 255
PTE880's
Kelford 272's

The car seems okay, but I am a little afraid to go WOT because of fuel issues that I am working out. In the meantime, can anyone offer advice on what modifications will need to be made to my timing map? It looks pretty aggressive to me, are these typically tuned down with the addition of larger cams? Thanks

 

Looks decent to me, what octane are you running? If it's 93 you should be fine, might be a bit aggressive for 91 octane though. Do you have any logs of the car? What fueling problems are you having?

 

Thank you Raptord. I am on 93 octane.

I was running lean because the injector scaling value was too high. I've reduced it to 770 and made a few latency changes, but have not yet flashed the ECU. I will flash and log tonight and post some better information.

 

Just wondering if you checked the Injector Scalling and latency supermerge, Im pretty sure the PTE880s would be in there as the PTE1000's were and the values I used there worked very well for me so far.

 

Yeah without seeing logs that timing map looks pretty spot on.

 

so i certainly wouldnt call this map fully tuned, but id certainly like some input since it is my very first attempt.

this is what is on the car currently (po had it tuned by someone from this board). there were tons of load columns that had no order, they jumped all over, so i attempted to smooth the whole thing out. there were also low load cells that had les timing than a stock rom which was very odd to me, so i fixed those too. i havent loaded my version, as i need to get my wideband to start working properly first.

on logs i typically hit 260 load, very occasionally 280 load. peak boost is usually 23.5psi. car is a stock turbo IX with TBE, perrin intake, ETS LICP, ETS 3.5 fmic, always on 93.

hrmmm.. first one is where i am now, second one is a trace. 26-27 or so psi stock ix turbo. hks cams. ive made minor tweaks here and there but you get the idea. i normally run about 22psi, but i tuned for higher aswe4ll.. thoughts?
